Hi Mike, As you know, your car has sensors at each of the four wheels that monitor the tire pressure at each tire. When these tire pressure sensors fail, you may notice inaccurate readings as to your tire pressure. In...

Hi Pat. Thanks for contacting us today. The codes you've listed are Dodge specific OBD-II codes that indicate that the Governor pressure sensor is either faulty or relaying false information to the ECU. This is likely the source of your...

I'm guessing the Battery and Oil Lights came on because the ignition was in the run position but the engine died. This is normal. What caused the vehicle to stall is another question. A vehicle that stalls and then...

Hi there. If oil is causing the spark plug on cylinder number 4 to foul out every 600 to 700 miles, then the valve guide seals to that cylinder are damaged and need replaced. The valve guide seals prevent excessive...

Hey there. Replacement of the throttle position sensor on your vehicle is pretty straight forward. There is no adjustment to be made - just remove and replace the sensor and you should be done. If the vehicle isn't starting, you...

Hello - not ideal, but certainly not fatal. You may even be able to remove the coolant reservoir, and drain the coolant/oil mix before any has gotten into the engine. Even if oil is in the coolant, a coolant drain,...

From what you've described, it sounds like you have a problem with your electronic throttle control system. Make sure your battery is good, if it is you may need to replace your throttle control valve to fix this issue in...

Hi there. When the fuel system gets low on fuel and the engine is still running and the engine stalls, there is a great possibility that the fuel system may have air in it. Put on a test line on...

Hi there. From the description you provided, your vehicle has problems with the transmission again. You stated it will not shift into 3rd gear again, like before the transmission was rebuilt. If the transmission is again the problem, it should...

The possible causes of this intermittent loss of power include a faulty oxygen sensor, weak fuel pump and/or clogged filter, vacuum leaks, ignition system malfunctions, bad valve timing if the timing belt or chain is worn or skipped, blocked exhaust...

Hi there. If the engine continues to overheat after fixing a core plug leaking, then the thermostat may not be opening all the way and needs replaced. As far as the vehicle not wanting to move and seems like the...

Hi there. There is a gear train issue with your transmission or a bad CV Shaft that is causing the transmission to shift had into gear. Since it shifts harder in reverse than forward, I suggest that the gears inside...

Since this involves something that is a matter of a safety, we are not allowed to definitively comment on whether or not this would be illegal. You will need to check with your state's transportation safety department with regard to...

The warning light means that the engine immobilizer system has detected a fault and/or is not recognizing the key. You can attempt to reset the whole system by removing the key from the car. Then, disconnect the negative battery cable...

This is likely related to what is called a speed input/output shaft sensor which is a sensor mounted down on the transmission that monitors the speed of the output shaft of the transmission. This is relayed to your ECU which...

If you do not have any problems with the engine getting low on coolant then the water dripping from the muffler is normal condensation dripping from the muffler. Most mufflers have a small drain hole on the bottom low side...
